While this is true, something to keep in mind is that the liquidity of the market is finite. The market may be able to hold SPCX up currently but adding an additional $100b (and much more as the lockup periods end) plus whatever OpenAI ends up offering might be too much for a lot of these pensions and the other buyers of these shares can manage. They will naturally get included in the indices as they become able to but the question is whether or not all 6 trillion of collective market cap they're attempting to offload will be able to be held up with time. My working theory is that they're aware of this fact to and it's been part of the reason they've been rushing to the door with these IPOs and non-standard lockup periods.
